Rated for 2 to 8 ohms in Stereo mode, 4 to 

16 ohms in Bridge-Mono mode. The XTi 1000 

A1 (100V version) is rated for 4 to 8 ohms 

Stereo, 8 to 16 ohms Bridge Mono.

Sensitivity:

 1.4V

Signal to Noise Ratio (below rated 1 kHz 

power at 8 ohms):

weighted). XTi 6K: 103 dB (A weighted).

Damping Factor:

 Better than 500 from 20 Hz  

to 400 Hz.

Crosstalk:

 > 70 dB below rated power, 20 Hz 

to 1 kHz.

Input Stage:

 Input is electronically balanced 

and employs precision 1% resistors.

Input Impedance (nominal):

 20 k ohms, bal-

anced;10 k ohms, unbalanced.

Maximum Input Signal:

 +22 dBu typical.

AC Line Voltage and Frequency Configura-

tions Available: 

100V, 120V, 220-240V  

50/60 Hz.   

AC Line Current 

(120VAC amplifier playing 

1/8 power pink noise into 4 ohms per ch): 

XTi 1000: 6.8A, XTi 2000: 8.3A, XTi 4000: 

10.5A; at idle draws no more than 38 watts.
XTi 6000: 15.3A; at idle draws no more than 

180 watts.

Operating Temperature:

 0° C to 40° C at 

95% relative humidity (non-condensing). 

DSP Section

Input EQ:

 6 parametric filters per channel with 

adjustable Q, ±15 dB boost/cut. Also adjust-

able high and low shelving filters. This 8-filter 

EQ section can be bypassed.

Crossover Filters:

 Highpass and lowpass 

per channel. Butterworth 6/12/18/24 dB per 

octave. Linkwitz-Riley 24/48 dB per octave. 

Also includes ±15 dB bandpass gain and 

polarity control. 

Delay:

 For signal alignment of driver; 50 mS 

total delay.

Subharmonic Synthesizer:

 Takes the low-

frequency content of the input signal and 

“synthesizes” a new signal that is the same 

as the input signal but one octave lower. The 

new synthesized signal is then mixed with the 

original signal to create the effect.

Output Limiter:

 Prevents clipping.

Presets:

 20 presets, 19 of which are user-

definable.

Front Panel Controls and Indicators

Level:

 Detented rotary level control, one per 

channel.

Power Switch:

 On/off switch applies AC 

power to the amplifier.

Sel/Prev/Next Buttons:

 Three buttons near 

the LCD screen are used to access menu 

items and  front panel lockout.

LCD Screen:

 Backlit liquid crystal display 

shows speaker presets.

Signal Indicator:

 Green LED, one per chan-

nel, illuminates when a very low-level signal 

is present at input. May be used for trouble-

shooting cable runs.

–10 Indicator:

 Green LED flashes when 

output signal exceeds –10 dB below clip.

–20 Indicator:

 Green LED flashes when 

output signal level exceeds –20 dB below clip.

Ready Indicator: 

Green LED, one per chan-

nel, illuminates when the amplifier is ready to 

produce audio.

Clip Indicator:

 Red LED, one per channel, 

turns on at the threshold of audible distortion.

Temp Indicator:

 Red LED, one per channel, 

illuminates under excessive temperature 

conditions. 

Power Indicator:

 Blue LED illuminates when 

the amplifier has been turned on and has 

power. 

Rear Panel Controls and Connectors 

AC Line Connector:

 

XTi 1K, 2K, 4K: NEMA 5-15P (15A). 

XTi 6K: NEMA 6-20P (20A)
IEC C20 (20A)

Input Connector: 

XLR, one per channel.

Link/Out Connector:

 Loop-thru signal from 

input connector for linking to another ampli-

fier, one per channel.

Output Connectors:

 Two Neutrik® Speakon® 

NL4MP (mates with NL4FC) output connec-

tors. Channel-1 Speakon® is wired with Ch. 1 

and Ch. 2 outputs for use with optional single 

4-conductor cable. Two binding post outputs 

(in parallel with Speakon® connectors).

HiQnet USB Connector:

 Type B, connects to a 

HiQnet network.

Protection

XTi-Series amplifiers are protected against 

shorted, open or mismatched loads; over-

loaded power supplies; excessive tempera-

ture; chain destruction phenomena; excessive 

output current, input overload damage; and 

high-frequency blowups. They also protect 

loudspeakers from input/output DC, large or 

dangerous DC offsets and turn-on/turn-off 

transients.

T

he XTi Series of Crown

®

 amplifiers are professional tools designed and built for portable PA applica-

tions. The series includes four models which are similar except for output power: XTi 1000, 2000, 

4000 and 6000. All are rugged and lightweight, and offer unmatched value in their class. XTi-Series 

amplifiers feature an LCD screen with speaker presets for crossover frequencies, EQ, limiting, delay, 

and a subharmonic synthesizer. Other features include a switch-mode universal power supply, useful 

function indicators, proportional-speed fan-assisted cooling, XLR inputs, Speakon

®

 and binding-post 

outputs, short-circuit protection and more.
